What Is Blockchain In Technology – Blockchain, derived from Bitcoin/Bitcoin, is having a very exciting moment all over the world, and its real value goes far beyond cryptocurrencies or money transfers.
Blockchain technology, the foundation of the cryptocurrency bitcoin, emerged in 2008-2009 when Satoshi Nakatomo, the creator of the open-source Bitcoin project, published the Bitcoin* protocol in a document describing a technological architecture for the free circulation of cryptocurrency without a central control panel. body . and without operating costs, as occurs in the circulation of money.

What Is Blockchain In Technology
And a completely new way compared to before, many types of transactions: from event registration, document signing, voting, citizen identity management and contracts.
Blockchain Technology: Definitions, Perspectives And Opportunities Not Only In The Finance Area
Proving that this is just a passing fad, thousands of developers and dozens of companies are already experimenting with the potential applications: estimates show that the annual growth rate of the market between now and 2022 will be can reach 80%.
*Bitcoin with a capital B represents the underlying technology that allows the virtual currency to circulate, while bitcoin with a lowercase b represents the currency.
This brief premise is necessary because it is from this document that the basic concept of Blockchain originated, a term that usually refers to a technological infrastructure, thus moving away from the origins of Bitcoin / bitcoin.
For maximum simplification, Blockchain can be thought of as a large distributed database protected by “public-private key” encryption (i.e., asymmetric or symmetric algorithms based on the use of keys to encrypt and decrypt information) and hash encryption (in this case). in this case we are talking about a one-way mathematical algorithm that is difficult to change, often used for digital signatures for example) to manage operations that can be shared between several network nodes.
The Use Of Blockchain In The Financial, Public And Other Sectors
In other words, it is presented as a structured database of blocks (where each block contains the information of several transactions) connected to each other over the Internet: every transaction initiated in that network (and therefore the Blockchain in question) must be confirmed by the network. itself, and then performing some block analysis and validation of each network (or circuit) component.
It is for this reason that the term “trust” or “trust mechanism” is often used when analyzing the structure and benefits of Blockchain. In fact, this type of technological architecture introduces several concepts of a social nature that until now have not been easily linked to the world of economics and technology.
From this, we conclude that the Blockchain system no longer requires a central governing body, and the chain is built on a trust mechanism where anyone can view and verify the entire Blockchain.
Control is then transferred to “nodes” (computers distributed around the world that are not controlled by any central administration): each node in the chain is responsible for reviewing, controlling and validating all transactions, creating a network that shares storage for the whole. Blockchain at each node (i.e. the entire database, i.e. all the blocks containing all the transactions).
Blockchain And Supply Chain Management
This explanation is by no means trivial and has a deep meaning, because it is from the difference between transactions and blocks that we also understand the role of the so-called “miners”, that is, those who create these blocks and put them in the Blockchain.
Although transactions can be made by anyone/user who wants to participate or use a particular Blockchain, the blocks containing the traces of these transactions must be created
Are incentivized for their work using a “reward system”, namely for controlling transactions and creating blocks included in the blockchain. For example, in the Bitcoin model, this is a reward that includes cryptocurrency shares. This is to avoid behavior that could lead to a decrease in the “distributed trust” of the community participating in the Blockchain.
We often hear about a distributed ledger, which refers to a distributed database that takes its name from the world of finance, reminiscent of a “book”, that is, a bank’s ledger, where all transactions are recorded.

In addition, it could enable the exchange not only of money, as Bitcoin originally did, but of any asset, information or contract, based on the mutual trust of all exchange participants.
It is indeed a concept that has the potential to transform the social, economic, and even governmental and political models that are currently the pillars of our modern world.
While the development and maturity of Blockchain may be accompanied by skepticism and fear, market analysis points to a phenomenon that is destined to be highly influential in the coming years.
Markets & Markets estimates that the market will grow from $411.5 million. USD in 2017 to more than 7 billion USD in 2022 at a compound annual growth rate (CAGR) of 79.6%.
What Is Blockchain Technology And How Does It Work?
According to the American analyst, the growth was mainly due to the reduction of TCO (total Final Cost of Ownership of the Blockchain) due to faster transactions, simplified business processes based on transparency and immutability, and, of course, increasing market capitalization. cryptocurrencies and ICO (Initial Coin Offering, initial amount of money).
Tractica’s latest report provides a more in-depth and specific analysis of the enterprise Blockchain applications market and predicts that by 2025 it will reach 19.9 billion
These use cases will also impact at least 19 different fields, including the world of finance, as well as healthcare, manufacturing, law and the public sector.
Currently, the analysis and understanding of Blockchain technology is led by the financial sector.
How Does Blockchain Work?
For example, many banks join the R3 consortium (a consortium of 40 leading global banks, including Italian institutions Intesa Sanpaolo and Unicredit) or open their own research centers where they can test and develop pilot projects to understand how the technology works in Blockchain, understanding all its possibilities.
Alternatively, the Commonwealth Bank of Australia is using the Ripple protocol, a private Blockchain, to transfer payments between its subsidiaries to test whether it might be possible to take full advantage of blockchain architecture due to transaction speed and lower fees.
Finally, as part of the so-called travel identity, travel industry specialist Sita has developed a Blockchain-based solution to provide travelers with unique and secure biometric identities. This project, created in collaboration with ShoCard, a startup specializing in Blockchain, is based on the idea that all passengers can have verifiable tokens with biometric and personal data on their mobile and portable devices. By simply using blockchain-embedded biometrics and verifying identity with a simple token on a mobile device, authorities can verify a person’s identity without asking for traditional documents like a passport.
Although this is an experimental project, from these examples we already understand the potential of Blockchain technology and hypothetical business scenarios: it will still be some time before a phenomenon that surpasses the background noise of Bitcoin and cryptocurrencies will be realized in reality, but the path seems to be set.

Blockchain is a distributed database or ledger that is shared between nodes in a computer network. They are best known for their important role in cryptocurrency systems in maintaining secure and decentralized records of transactions, but they are not limited to cryptocurrency applications. Blockchain can be used to make data immutable, a term used to describe immutability, in any industry.
Since there is no way to change blocks, the only trust required is where the user or application enters the data. This aspect reduces the need for a trusted third party, which is usually an accountant or someone else who adds costs and makes mistakes.
Blockchain: How Blockchain Technology Functions
Since the introduction of Bitcoin in 2009, the use of Blockchain has exploded due to the development of various cryptocurrencies, decentralized finance (DeFi) applications, non-fungible tokens (NFTs) and smart contracts.
You may be familiar with spreadsheets or databases. Blockchain is somewhat similar in that it is a database where information is entered and stored. However, the main difference between a traditional database or spreadsheet and a blockchain is the structure and access to the data.
Blockchain consists of programs called scripts that perform the tasks you would normally perform in a database: entering and accessing information and storing and storing it. Blockchain is distributed, meaning that multiple copies are stored on multiple devices and all must match to be valid.
Blockchain collects transaction information and puts it into blocks, like spreadsheet cells that contain information. Once the information is filled in, it is run through an encryption algorithm that creates a hexadecimal number called a hash.

The hash is then inserted into the header of the next block and encrypted with the rest of the block’s information. This creates a chained series of blocks
